str = computer
archstr = computer('arch')
[str,maxsize] = computer
[str,maxsize,endian] = computer

Description

str = computer returns the computer type on which MATLAB® is running.

archstr = computer('arch') returns the system architecture. The mex command and standalone applications use this value to locate MATLAB library files.

[str,maxsize] = computer returns the maximum number of elements allowed in an array with this version of MATLAB.

[str,maxsize,endian] = computer returns the endian byte order format.
